Fishing overflow creeks

[CMorg]

I just went to my local lake , its 1,400 acres of water. There is an overflow pipe that runs out the other side of the levee into a creek that just happens to run 2 miles to the river.. I was just curious today and stopped to check it out , then when I seen the size of fish in there I decided to fish it , anyway long story short I threw cranks , senkos , creature baits , and my chatterbait , got one small peck but nothing else.. I could actually see 4 large fish staged in front of a pipe that goes across the road , as if to eat everything that tried to get threw... HELP !!! These were big fish..
